Offered no resistance.

Explanation:

Because of tactics by Hitler (ex. Blitzkrieg) other European nations lacked both the manpower, environment, and time to help other nations when they were attacked in the beginning of World War 2. In conventions like the Munich Conference, they were even forced to negotiate territories like Czechoslovakia with Germany.

This is not correct statement.

Explanation: United Kingdom opted for strategy called "appeasement", i.e. conservative government of Neville Chamberlain tried to satisfy German (i.e. NSDAP´s or Hitler´s) requirements. There was no "immediate armed resistance" neither in the UK nor in France. There was no strong opposition in Germany either. Hitler was legally elected, he had enormous support in Germany and in Europe nobody wanted an armed confrontation. Munich conference (1938) was a way how to "transfer" Czechoslovakian "Sudetenland" to the III Reich in a "democratic" way Munich conference took place among Britain, France, Germany and Italy...all the parties involved approved occupation of Sudetenland by Germans.
